That's on the higher end of household usage. On the lower end, during a cold windstorm in the PNW I was able to get it down to 600W (15 kWh/day) because I have mostly natural gas appliances. My Cybertruck kept us going for nearly a week with just one top-up (because I don't like to go above 80% or below 20%). We deferred using the dryer and dishwasher, and relied on the fireplace for warmth instead of the HVAC.

On a hot day yeah I'd be running the A/C but ideally you'd have solar to offset much of that.

You could get something like a Span electrical panel and only enable critical loads during a blackout and set the AC a little higher than normal. Even a large house can go down to 20-30 kWh a day.

On the other here in Washington a little west of Seattle with a 3 bedroom all electric house I use about 40 kWh a day in the coldest month of winter and 8-10 kWh a day in summer.
